helper needed

I am going to a show in london on 6 july. It is londo film and comic book convention at earls court and I will be going as wonder woman. And I am collecting for Muscular dystrophy. I could use a helper, Just to take pictures- carry an empty back pack, make sure I stay decent. I will provide camera and entry ticket. As i will be dressed as wonder woman, it would help if the helper was female, Is there any one in london who would like to help please? I can give more details when needed.

Last year i was able to raise £3100 though out the year.

Thank you
phil
